Cataclysmic Era: I can unlock the tech tree

a mess.

The moment he saw the image, this phrase instantly came to mind for Lü Yongchang.

Beside the open gate lay several corpses dressed in black.

Without a doubt, these must be deceased Proxima Centauri inhabitants.

They were smashed into a pulpy mess by some stones and metal blocks.

Pools of bluish-green substance flowed from these corpses, and after drying, they formed patches of blue and black on the ground.

This extremely impactful scene was presented to everyone.

"Blue blood." Lü Yongchang frowned slightly and muttered to himself, "The time since death must have been quite long."

"These bodies and the blood showed signs of decomposition."

"Zero, look around and see if there's a relatively intact body."

Fang Xu, who was standing nearby, had obviously heard his muttering and immediately gave him a horrified look.

Almost at the same time, Lü Yongchang noticed the strange look Fang Xu was giving him.

He looked up at Fang Xu, a bright smile spreading across his face: "Calm down, you get used to this stuff after a while."

"Next time I'll take you to the biology lab to train."

Fang Xu: "..."

The holographic projection image began to change again.

After rotating in several directions, the screen suddenly stopped.

Clearly, Zero has found his goal.

The camera began to zoom in.

Next to the main gate, there is a disc-shaped control panel.

Beside the control panel, a relatively intact corpse lay quietly.

The robot quickly approached.

Then, he extended his mechanical arm and "grabbed" him off the chair, laying him flat on the ground.

At this moment, humanity finally saw the true face of the Proxima Centauri.

"..."

The control center was completely silent.

"Why does it feel... a bit like a large cockroach?" Zhao Zijie's hesitant voice came.

Lu Yongchang's expression also turned strange.

Zhao Zijie was right; at first glance, its shape did indeed resemble a large cockroach.

A hard, shell-like back.

Three pairs of feet.

The difference between them and cockroaches is that Proxima Centauri has two pairs of extremely strong forelimbs and hindlimbs, as well as a pair of almost completely degenerated accessory limbs.

Of course, the biggest difference lies in the head.

The Proxima Centauri had three pairs of eyes.

On the top of the head, there is a patch of skin covered with fine bumps.

"hiss……"

It must be said that even though he was mentally prepared, Lü Yongchang still couldn't help but gasp when he saw such a bizarre scene.

"Zero, preserve this body for now, and bring it back to the biology lab once it's confirmed to be safe."

Upon hearing this, Fang Xu's expression changed drastically.

After imagining the scene, he gagged twice, feeling nauseous.

Lu Yongchang naturally ignored the retching sounds coming from beside him. He controlled the camera's angle to rotate a few times before speaking in a low voice.

"It seems that this genetic weapon isn't particularly effective."

"The genetic information we obtained before was indeed problematic."

"What do you mean?" Fang Xu asked Lü Yongchang, forcing himself to suppress his nausea.

"Look, these Proxima Centauri people show obvious signs of struggle." Lü Yongchang waved his hand in the air, magnifying several images several times. "This means they have some resistance to this genetic weapon."

"As I anticipated, once this genetic weapon takes effect, it will absolutely not give them a chance to struggle."

"At least, they will die unconsciously."

"Instead of struggling to escape."

As he spoke, he mentally recreated the chaotic scene from that time.

Several Proxima Centauri ran to the tightly closed gates of the underground city, attempting to escape from it.

A Proxima Centauri arrived at the control panel and opened the tightly closed door.

The tragedy ensued.

Boulders and metal blocks rained down, smashing the unfortunate Proxima Centauri into a pulp!

"Forget about that for now." Lü Yongchang shook his head, banishing the imagined scene from his mind. "Zero, keep moving forward."

……

The underground city is littered with the corpses of Proxima Centauri.

There are also monitors and consoles of various sizes.

Unfortunately, after the robot's inspection, it was found that these monitors and consoles were damaged.

At least for now, they are unable to extract any valuable data from it.

Upon hearing this news, Lü Yongchang shook his head with a look of regret.

What a pity!

Before he could finish his exclamation, an exciting notification popped up.

A robot discovered an area sealed off by a heavy door.

It looks like the core area of ​​the underground city.

As for why this judgment was made...

It's very simple; several Proxima Centauri characters are clearly marked on this door.

After being translated by Ling, these words were converted into Chinese characters and presented to Lü Yongchang.

[Core Area]

Unlike the other areas, the access control in the core area is clearly in normal working order.

The monitor next to the gate also glowed softly.

Lu Yongchang's eyes flickered slightly, stopping the crude and simplistic attempt to forcibly break through the defenses with the unprepared high-energy laser beam.

"Zero, try and see if you can hack into their central computer through this access control system."

……

Inside the Mysterious Maiden II on the Earth's surface, a large 3D printer, specially installed for this mission, begins to operate.

Based on Zero's simulation calculations, it rapidly manufactured various "hardware tools" that conformed to the standards of the Proxima Centauri civilization.

Once the manufacturing was complete, a robot carrying these tools took an elevator and quickly arrived at the access control.

then……

It's the same process again.

3D printers have begun manufacturing corresponding adapters.

After several hours, Zero finally succeeded in "entering" the Proxima Centauri civilization's access control system through the robot.

One second later.

The sound of the transmission mechanism rang out.

The heavy, tightly closed door slowly opened.

"Zero?" Lu Yongchang's eyes showed a hint of surprise as he asked in a low voice, "That simple?"

Perhaps to better explain the reason, Zero projected his virtual image in front of everyone.

"Professor, the Proxima Centauri civilization does not have artificial intelligence."

"There isn't even weak artificial intelligence."

"Their software development level is roughly equivalent to...humans in 2030."

Upon hearing this, Lü Yongchang was momentarily stunned.

So backward?!

No wonder Zero found the vulnerability in the opponent's defense program so easily back then...

Zero's voice continued to ring out.

"I successfully accessed the central computer through their access control system."

"Professor, there's something you'd be very interested in."

Lu Yongchang asked instinctively, "What?"

The densely packed Proxima Centauri script appeared on the giant holographic projection.

Photonic computing technology.
